Low-carbon island reef full-coral seawater concrete and preparation method thereof
The invention discloses a low-carbon island reef full-coral seawater concrete and a preparation method thereof, and the low-carbon island reef full-coral seawater concrete is prepared on site by adopting a method of taking abundant waste coral (sand) as coarse (fine) aggregate, taking coral micro powder as a main cementing material to replace part of cement, mixing seawater and curing. The concrete comprises the following raw materials: a low-carbon composite cementing material, crushed coral, coral sand, a high-efficiency additive, seawater and the like. The preparation method comprises the following steps: preparing the coral micro powder and preparing the low-carbon composite cementing material. Preparing the low-carbon island reef full-coral seawater concrete; and evaluating the mechanical property and the low-carbon property of the low-carbon island reef full-coral seawater concrete. The use amount of cement in the preparation process is reduced, the carbon emission in the concrete production process is reduced, the used raw materials can be obtained locally, energy consumption and CO2 emission caused by long-distance sea transportation of the raw materials are avoided, and the method has the advantages of being economical, environmentally friendly, convenient to obtain materials and the like.
本发明公开了一种低碳岛礁全珊瑚海水混凝土及其制备方法，采用岛礁丰富的废弃珊瑚(砂)作粗(细)骨料，珊瑚微粉作主要胶凝材料取代部分水泥、海水拌合和养护的方法，现场制备低碳岛礁全珊瑚海水混凝土。该混凝土包括以下原材料：低碳复合胶凝材料、破碎珊瑚、珊瑚砂、高效外加剂、海水等。制备过程包括以下步骤：珊瑚微粉的制备及低碳复合胶凝材料的配制；低碳岛礁全珊瑚海水混凝土的制备；低碳岛礁全珊瑚海水混凝土的力学性能及低碳性评估。本发明不仅减少了制备过程中水泥的用量，降低了混凝土生产过程中的碳排放量，而且使用的原材料可就地取材，避免了远距离海运原材料造成的能源消耗和CO2排放，具有经济、绿色和取材便捷等优势。
